Abstract

"VáLVULA DE CONTROLE DE COMPRESSOR DE DESLOCAMENTO VARIáVEL", usada para um compressor de deslocamento variável instalado em um circuito refrigerante de um condicionador de ar. O compressor possui um cárter (12) e uma passagem de controle (28), a qual conecta o cárter (12) a uma zona de pressão na qual a pressão é diferente da pressão da passagem de controle (28). A válvula de controle (CV) possui um corpo da válvula (46), que é acomodado em uma câmara de válvula (42) para ajuste do tamanho da abertura da passagem de controle (28). Um elemento sensor de pressão (48) move-se de acordo com a diferença de pressão entre dois pontos de monitoração de pressão (P1, P2) colocados no circuito refrigerante. O elemento sensor de pressão (48) move o corpo da válvula (46) tal que o deslocamento do compressor é variado para combater as mudanças na diferença de pressão. A força aplicada por um atuador (51) corresponde a um valor desejado da diferença de pressão. O elemento sensor de pressão (48) move o corpo da válvula (46) tal que a diferença de pressão busque o valor desejado. Um elemento de impulsão (64) é acomodado na câmara de válvula (42). O elemento de impulsão (64) força o corpo da válvula em uma direção para abrir a passagem de controle."VARIABLE DISPLACEMENT COMPRESSOR CONTROL VALVE", used for a variable displacement compressor installed in a refrigerant circuit of an air conditioner. The compressor has a crankcase (12) and a control passage (28), which connects the crankcase (12) to a pressure zone in which the pressure is different from the pressure of the control passage (28). The control valve (CV) has a valve body (46), which is accommodated in a valve chamber (42) for adjusting the size of the control passage opening (28). A pressure sensor element (48) moves according to the pressure difference between two pressure monitoring points (P1, P2) placed in the refrigerant circuit. The pressure sensor element (48) moves the valve body (46) such that the displacement of the compressor is varied to combat changes in the pressure difference. The force applied by an actuator (51) corresponds to a desired pressure difference value. The pressure sensor element (48) moves the valve body (46) such that the pressure difference seeks the desired value. A drive element (64) is accommodated in the valve chamber (42). The drive element (64) forces the valve body in one direction to open the control passage.
